Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a yarn feeding device for high-density knitted fabrics. Background Technology

[0002] In the fabric production process, different steps require different yarn guiding devices for guiding and supplying yarn to suit different production environments. Chinese utility model patent, authorized publication number "CN214733188U", discloses a yarn guiding device for knitted fabric production. By setting a limiting device, the yarn passes through the inner ring of the ring on the guide seat, restricting the yarn's position within the range of the inner ring, improving the stability of yarn conveying and preventing the yarn from falling off the guide wheel. Furthermore, the ring can rotate with the yarn; during yarn rotational deviation, the ring can rotate with the yarn's angle, reducing wear between the yarn and the inner ring and improving yarn conveying stability. Through multiple guide wheels in the yarn guiding device, the guide roller can be axially adjusted to adapt to different yarn positions, allowing specific yarns to be individually conveyed to specific positions, thus easily adapting to different fabric production requirements.

[0003] While the above-mentioned technical solution can guide and limit the yarn during use, the frequent friction of the yarn in the guide structure during the production of high-density knitted fabrics, due to the multiple limit seats being installed on the limit frame, easily generates fuzz and impurities. These fuzz and impurities adhere to the guide structure, which can easily lead to wear or damage. When one of the guide structures needs to be replaced, the entire limit frame needs to be disassembled, and then the worn part needs to be replaced. This makes the replacement and maintenance of the guide structure cumbersome and time-consuming. Therefore, we propose a yarn feeding device for high-density knitted fabrics. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a yarn feeding device for high-density knitted fabrics. This device can solve the problem that although it can limit and guide the yarn, because multiple limit seats are installed on the limit frame, the yarn is frequently rubbed in the guide structure during the production process of high-density knitted fabrics, which easily generates fuzz and impurities. These fuzz and impurities will adhere to the guide structure, which will easily lead to wear or damage to the guide structure. When one of the guide structures needs to be replaced, the entire limit frame needs to be disassembled, and then the worn one needs to be replaced. This makes the replacement and maintenance of the guide structure cumbersome and time-consuming.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-density knitted fabric yarn feeding device, comprising: The frame has two support plates fixedly connected to its top, and the inside of the frame is equipped with a yarn guiding structure.

Multiple bolts are connected to the internal threads of the corresponding threaded holes. Multiple limiting seats are fixedly installed on the limiting frame by corresponding bolts. Two corresponding limiting seats fit together. Multiple rings are rotatably connected inside the corresponding two limiting seats.

[0023] The yarn guiding structure includes two mounting seats 7, multiple guide wheels 5, and a guide shaft 4. The two mounting seats 7 are fixedly mounted on the corresponding support plates 6. The guide shaft 4 is fixedly connected to the opposite surfaces of the two mounting seats 7. The multiple guide wheels 5 are rotatably sleeved on the outer surface of the guide shaft 4. There are three yarn guiding structures. All three yarn guiding structures are set on the frame 1. The limiting frame 8 is fixedly mounted on the corresponding two mounting seats 7.

[0024] Furthermore, when using this device, the frame 1 of this high-density knitted fabric yarn feeding device has a "U"-shaped structure, serving as the basic support for the entire device and providing installation positions for other components. Inside the frame 1, guide roller 1 2 and guide roller 2 3 are rotatably installed. When the yarn enters the device, the yarn is first positioned by the ring 15, and then passes through the nearby guide wheel 5. Guide roller 1 2 and guide roller 2 3 provide initial guidance for the yarn, allowing it to enter the subsequent structure along a predetermined path. After being guided by the guide rollers, the yarn enters the area of ​​guide wheel 5. Guide wheel 5 can rotate around guide shaft 4. Multiple guide wheels 5 work together to further guide and comb the yarn, ensuring that the yarn remains stable and orderly during the conveying process, avoiding problems such as yarn tangling and knotting, and providing a guarantee for subsequent yarn positioning and accurate yarn feeding.

[0025] The limiting frame 8 is fixedly installed on two corresponding mounting seats 7. The through groove 13 inside the limiting frame 8 provides space for the yarn to pass through.

This design makes the installation of the limiting seat 12 more stable and facilitates disassembly and replacement.

[0026] Both ends of the inner ring 15 are provided with rounded corner structures. When the yarn passes through the ring 15, the rounded corner structures can reduce the friction between the yarn and the edge of the ring 15, preventing the yarn from being damaged due to friction. Multiple limiting rings 16 are fixedly sleeved on the outer surface of the corresponding ring 15 and are slidably connected inside the corresponding two limiting grooves 17. The cooperation of the limiting rings 16 and the limiting grooves 17 plays a limiting role for the ring 15, preventing the ring 15 from shifting during rotation, ensuring that the yarn can pass through the ring 15 smoothly, and keeping the yarn on a fixed path during the conveying process, achieving precise yarn limiting and ensuring accurate yarn supply when weaving high-density knitted fabrics.

[0027] Multiple limit seats 12 are fixedly installed by corresponding bolts 14. At the same time, multiple mounting plates 11 are slidably connected to corresponding mounting slots 9, making the installation of the limit seats 12 more stable and able to effectively withstand various forces generated during yarn conveying, ensuring the normal operation of the limit function. Moreover, it is easy to disassemble and replace. When a limit seat 12 is worn or damaged, it is not necessary to disassemble the limit frame 8 as a whole.
